Outsource Image Labeling Services

High-quality training data is a critical prerequisite for a successful Artificial Intelligence/Machine Learning model. But, alongside quality, the caliber of an AI/ML training data set is also determined by the scale and speed of annotation, data security, and mitigation of bias. Employing accurate image annotation for Machine Learning/AI projects while incorporating all these elements can help create a data set that’s appropriate for any particular planned project.

However, in the absence of professional annotators, businesses often face one or more of the following challenges-

  • Capturing the precise context of any image
  • Careful comprehension and attention to detail
  • Face recognition and subsequent analysis(identifying gender, classifying emotions, etc.)
  • Analyzing large databases while preserving accuracy
  • Sorting classifiers for any given image
  • Maintaining security compliances for the data
  • Maintaining consistency in subjective data sets

Altogether, this time-consuming process claims more effort and investment than reasonable when attempted in-house. That’s why it makes more business sense to outsource image annotation services to a reliable partner.

2D Bounding Boxes & 3D Cuboids

Perception models trained on our 2D bounding box annotation data sets can enhance your model’s visual search abilities by detecting different objects from most complex images. Our annotators employ the 2D bounding box & 3D bounding box annotation techniques for projects across various domains, including healthcare, agriculture, autonomous vehicles, eCommerce, traffic control, etc., that require the training data to:-

  • Teach self-driving cars to detect other vehicles, pedestrians, cyclists, footpaths, traffic lights, and other obstacles on the road- to simplify navigation
  • Teach retail and eCommerce models to recognize clothes, accessories, furniture, groceries, etc.- to simplify the checkout process or generate automatic billing
  • Teach computer vision models to recognize damage on objects, i.e., vehicles, buildings, etc. - to estimate the level of assistance required, to estimate insurance damages, etc.
  • Recognize objects, humans, pathways, etc. from satellite imagery or drone footage

Aided by precise image labeling services, we model our bounding box annotation workflow with your custom requirements to locate objects of interest.

Semantic Segmentation

With semantic segmentation, we enhance the quality of your training data set by detecting, classifying, and localizing objects in a particular area inside any image. It is a powerful tool that we utilize for image annotation in deep learning projects. Through color-coded, pixel-level annotation in images, we employ client-specific semantic labeling to help you solve problems like:-

  • Navigation for autonomous vehicles, robots, and drones
  • Detection of specific crop types, weeds, or land-types in a field
  • Differentiating healthy cells from tumor cells, analyzing blood flow, recognizing broken bones, etc. in medical diagnosis
  • Monitoring ecosystem damage using satellite imagery for large areas


By plotting points on an object’s vertices through polygon annotation, we can define its exact edges and ensure concentrated tagging and labeling.

  • Detecting water features
  • Recognizing asymmetrical objects, like logos, street signs, buildings, trees, etc.
  • Detailed recognition of facial features
  • To capture the shape and sizes of distant images in an object

Lines & Splines

We train our annotators on creative methods to define and label lines and boundaries of a wide variety in any image accurately. With our accurate line annotation services, we have fueled several vehicle perception models with accurate lane navigation learnings by:-

  • Annotating footpaths and sidewalks
  • Detecting different lanes on the road to simplify navigation for self-driving vehicles

Text Annotation

To make text strings and keywords comprehensible to ML and AI models, we offer multi-language text annotation services with metadata labeling. In addition to tagging text from different images into predetermined classifiers, our professional annotators also add a suitable description along with the annotated text to facilitate a faster and precise data visualization model.

This service can help train a computer vision model on accurate natural language interpretations. While businesses have several usages for text annotation, i.e., automated customer service, the most prominent use case is to teach ML/AI models to carry out a meaningful conversation with humans.

Video Annotation

With frame-by-frame annotation for videos of varying lengths, we equip your training data sets with information on the simple classification of moving objects. Every video is converted into a sum of short clips by our processing experts, who apply a combination of different annotation techniques to glean the vital information from each frame with precision. The resultant data set can help your AI/ML models in various ways:-

  • Teach autonomous vehicles to track moving objects
  • Track human activities and interpret poses and facial expressions
  • Estimation of motion for autonomous vehicles, drones, etc.

Point/Landmark Annotation

With the landmark annotation services from SunTec India, you can train your model to detect minute shapes and sizes in any image or video with appropriate precision. By plotting sequential dots at specific locations in an image, we create accurate data sets that can teach deep learning models about the trajectory of moving objects in an image and estimating the same with increased precision.

Its most popular use-cases involve:-

  • Face recognition
  • Identifying postures in athletes for enhanced sports analytics
  • Recognizing facial expressions, features, and emotions
  • Precise gesture detection
